My wife and I went for a few hours inflate June. It's a really neat spot and the non profit running it has done great job with it. The pool itself is very cool and crystal clear. There is a large lawn area for laying out towels and chairs. There are rope swings for the kids and young at heart. There are bathrooms at the entry gate.
You can take a picnic or snacks. The rules say no alcohol is allowed. We had a 6 pack of beer and no one bothered us. I would guess that if you aren't acting the fool they'll leave you alone but I only have a few hours there to base that on.
Only reason I don't give it 5 stars is that it was $8 per person. Seemed a little high but was still a lot of fun.
